With winter holidays come and gone, travelers’ thoughts are turning to spring, summer, and beyond. And while there are plenty of suggestions about where to go, major websites where consumers look (and book) have come out with their own lists of where we’re really going.

Though we're barely a few weeks into the year, some trends stand out:

Flying High

If airfares don’t go up (and some experts are predicting fares may even drop slightly in some markets), then cities where several airlines compete will do well the first part of 2016. According to Expedia, coach air tickets declined overall about 8 percent through October of last year and that trend should continue through the first few months of the year.

When to buy is another hot topic. Expedia says that if you’re just flying in the U.S., then around 57 days in advance is an optimal lead time, for but international destinations, at least 176 days ahead is recommended.

What's Trending

Priceline.com has come out with its top 25 destinations for 2016 based on advance hotel reservations last year, and topping the list are Las Vegas, Orlando, Miami, New York City and San Francisco—all of which are easily accessible by air, with a mix of major airline and discount carrier traffic.

With the exception of Chicago, the rest of Priceline’s top 10 are in the Sunbelt: Fort Lauderdale, New Orleans, Orange Country, California, and Los Angeles. The trend continues: No fewer than six of the top 25 are in the Sunshine State (the others being the Florida Keys, Tampa, and Fort Myers); Phoenix, Atlanta, and Puerto Rico, San Diego, and Honolulu are also top vacation spots. The top foreign destination—in the Priceline survey, anyway—is Cancun/Cozumel.

For its part, Skyscanner.com has also spotted an increase in domestic travel, which accounts for more than half, or 51.6 percent, of all bookings made by U.S. travelers, up from 49.5 percent the previous year. Cities that are trending up in searches recently include Dallas, Atlanta, Phoenix, Tampa, and Philadelphia; however, New York City and Las Vegas are trending down slightly.

Other destinations ranking high in Skyscanner’s search activity include Puerto Rico, Colombia, the Philippines, and Cuba—which, unsurprisingly, is up nearly 90 percent from the previous year due to the restoration of diplomatic ties with the U.S. last year. It's unclear how much of this interest translated into actual bookings, however, given that trips to Cuba for pure tourism are still off-limits for Americans.

One surprise? Bookings to China were down by 23 percent, and, despite a stronger dollar, U.S. travel to key European gateways also decreased last year when measured by Skyscanner bookings—the U.K., Italy, and Germany all registered drops of more than 10 percent. True, airfares across the pond have risen sharply in the last few years. But once you get there, air travel is a bargain: according to Expedia, discount carriers have kept fares down within the continent, declaring 2016 to be “a great year to travel to Europe and hop around by plane.”
